Definitions

  • Such a stop has a mounting base from which an outwardly extending machining head motion-limiting abutment arm is disposed in operable cooperation with the slide arrangement that accordingly limits machining head, tool and bit starting position or height, movement, and/or range of travel.
  • the abutment arm of the stop interferes with movement of the movable slide block, machining head, tool and bit when a designated starting or stopping position or range of travel has been reached.
  • the abutment arm of the stop interferes with movement of the movable slide block of the slide arrangement which thereby in turn interferes with movement of the machining head, tool and bit when the designated starting or stopping position or range of travel defined by the stop has been reached.
  • the machine mount 32 is a magnetic mount 36 configured for releasable mounting to a magnetically attractive mounting surface 34 that can be the outer or top surface of a die 24 mounted in a stamping press 26 or a magnetically attractive workholding surface, e.g., workbench or table, located in a tool room (not shown) where the die 24 is being prepared for use in a stamping press 26.
  • a magnetic mount 36 can include an actuator 38, such as a lever or knob 40, used to
  • the horizontally displaceable slide plate 50 of the horizontal slide arrangement 46 moves a machining head carriage 74 substantially in unison therewith.
  • the carriage 74 includes a carriage mount 76 carried by the slide plate 50 and a machining head support 78 oriented generally perpendicularly or orthogonally relative to the direction of motion of the slide arrangement 46.
  • the machining head support 78 extends generally vertically relative to the slide plate 50 with the carriage mount 76 extending generally outwardly from the machining head support 78 overlying at least a portion of the slide plate 50.
  • the second slide 102 is a machining head slide arrangement 104 formed of a slide block arrangement as shown in Figures 2-4 that includes a front movable slide block 106b that is movably coupled, preferably slidably coupled, to a rear slide block 106a that is fixed to the swivel plate 90, which is in turn grounded to the machining head carriage 74 when the angular adjustment clamping knob 98 is tightened.
  • the retainer preferably fastener, more preferably thumbscrew 123 is manipulated, preferably manually rotated, when engaged with both clamping blocks 112 and 114 clamped around the tool housing 118 to selectively apply an amount of clamping pressure to the housing 118 that is enough to hold the tool 80 in the tool holder 105 while enabling the tool 80 to be slidably moved relative to the clamping blocks 112 and 114 closer to or farther away from the die cavity 25 to a desired setup position prior to use of the machine 20.
  • the machining head downward travel limiting stop landing 163 is grounded, e.g., is part of ground, by being fixed to ground during slug retention groove forming use of the machine 20 by the stop landing 163 being fixed to part of the machine 20 that is ultimately fixed or grounded to machine base 30.
  • the stop landing 163 is provided or defined by at least a portion of an upper or top edge 155 of an opposite end, i.e., the top 155, of the fixed slide block 106a.
  • stop mounts 188, 190 respectively include spaced apart stop mounting fasteners 192, 194 which extend through corresponding spaced apart stop mounting slots 196, 198 formed in stop mounting base plate 184 into engagement with outboard edge or side 191 of swivel plate 90 during both position-adjustable mounting of stop 180a to swivel plate 90 and position-fixing grounding of stop 180a to swivel plate 90.
  • stop mount 188 includes one fastener 192 that extends through one elongate generally vertically extending slot 196 into engagement, preferably threaded engagement, with part of the outboard edge or side 191 of swivel plate 90
  • stop mount 190 includes another fastener 194 that extends through another elongate generally vertically extending slot 198 into engagement, preferably threadable engagement, with another part of the outboard edge or side 191 of swivel plate 90 during both adjustable-position mounting and position-fixing grounding of the stop 180a.
  • the motion limiting abutment arm 208 of position- fixed grounded stop 180a interferes with additional downward travel of the head 28, tool 80 and bit 82 when the stop arm 171 comes into contact therewith to limit the extent or distance of downward machining head travel to an extent or distance less than the maximum when no stop 180a, 180b, or 180c is mounted to the machine 20.
  • machining head travel range or distance of at least one inch when no stop 180a, 180b or 180c is used use of such a "speed" stop 180b reduces slug retention groove machining time by at least 25%, and in many instances, reduces slug retention groove machining time by at least 40% as compared to when no stop 180a, 180b or 180c is mounted to the machine 20.
  • Figures 10-12 illustrate a preferred embodiment of a third stop 180c that preferably is an adjustable machining head travel range limiting stop 180c that is similar in construction to the "speed" machining head travel range limiting stop 180b of Figures 8-9, but which additionally includes a manipulable upper or return machining head travel range- limiting adjuster 240 that is manually adjustable by user to increase or decrease the maximum machining head travel range provided by the fixed stop machining head travel limiting stop arm travel range-defining recess 222 defined by the distance between the fixed upper and lower abutment arms 224 and 226 of stop 180b.
  • a manipulable upper or return machining head travel range- limiting adjuster 240 that is manually adjustable by user to increase or decrease the maximum machining head travel range provided by the fixed stop machining head travel limiting stop arm travel range-defining recess 222 defined by the distance between the fixed upper and lower abutment arms 224 and 226 of stop 180b.
  • the adjustably extensible stop post 244, and more specifically the thumbscrew 248, can and preferably does provide a slow or precision movement machining head drive 264 ( Figure 10) when displaced, preferably via rotation, in a direction that causes the position-adjustable upper abutment arm 245 of the stop end 242 to bear against the damper arrangement 168, e.g. bumper 170, displacing damper arrangement 168 stop arm 171, head 28, tool 80 and bit 82 substantially in unison such that stop end or adjustable upper abutment arm displacement thereby slowly and precisely moves the head 28, tool 80 and bit 82 toward the die cavity 25 and into slug retention groove machining contact with the sidewall 27 of cavity 25 during machining of groove 22.
  • the damper arrangement 168 e.g. bumper 170, displacing damper arrangement 168 stop arm 171, head 28, tool 80 and bit 82 substantially in unison such that stop end or adjustable upper abutment arm displacement thereby slowly and precisely moves the head 28, tool 80 and bit 82 toward the die
  • base 30 is anchored to the die 24 and the horizontal drive 49 is manipulated by the user to cause the horizontal slide arrangement 46 to horizontally displace the head 28, tool 80 and bit 82 relative to the upper or outer edge of the sidewall 27 so that the machining bit 82 is more precisely located, e.g., micro-positioned, generally above and adjacent thereto.
  • the horizontal slide drive 49 is manipulated by the user to more precisely horizontally position the bit 82 so that the bit 82 preferably will come into contact with the sidewall 27 when vertically displaced downwardly toward and into the cavity 25 during machining of the groove 22.
  • biasing element 160 urges the movable slide block 106b and head 28 upwardly in a direction away from the die cavity 25 until the damper arrangement 168 and travel limiting stop arm 171 abuts against upper abutment arm 224 or 245 retaining the bit 82 in a preset uppermost return travel position that corresponds to the desired pre-slug retention groove machining setup position and height readying the machine 20 to machine groove 22.
  • the camera mounting base 142 preferably also is of magnetic construction defining or providing a mounting base 142 that releasably, yet securely, e.g., generally immovably, adheres the camera support 140 to the outer surface 34 of die 24 adjacent the cavity 25 on a side of the cavity 25 opposite the sidewall 27 in which groove 22 is machined or is going to be machined.

La présente invention concerne une machine portable et transportable de modification de cavité de matrice présentant une base portant un chariot ajustable le long d'un axe, par exemple, un axe généralement horizontal, et une tête d'usinage ajustable le long d'un autre axe, par exemple, un axe généralement vertical, pour modifier une cavité de matrice d'une matrice d'estampage de manière à empêcher toute traction du flanc ou de l'ébauche lors du fonctionnement de la presse à estamper. La machine comprend une butée qui est raccordée de manière ajustable au chariot. La butée est conçue pour limiter le mouvement de la tête d'usinage le long de l'axe généralement vertical. La machine peut également comprendre un isolateur de vibrations qui est utilisé avec la butée pour empêcher le bruit et les vibrations qui résultent du mouvement de la tête d'usinage par rapport à la butée. De plus, la machine peut comprendre un dispositif optique capable de capturer une image de la cavité de matrice définissant la paroi latérale à mesure que le trépan de meulage rotatif usine la rainure de retenue de bouchon allongée.
